Description

Technical Field

[0001] The present invention relates to the technical field of accessories for machining centers, and particularly to a rotary table for a horizontal machining center. Background Art

[0002] A numerically controlled machining center is an automatic machining device developed on the basis of a general milling machine. The machining center has the ability to automatically exchange machining tools. By installing different-purpose tools on the tool magazine, the machining tool on the spindle can be changed through an automatic tool changer during one clamping, realizing multiple machining functions. Machining centers are often classified into vertical machining centers and horizontal machining centers according to the state of the spindle in space. When the spindle of the machining center is in a vertical state in space, it is called a vertical machining center, and when the spindle is in a horizontal state in space, it is called a horizontal machining center. With the development of modern manufacturing, personalized customized products have become the trend, but the requirements for products have further increased, and the cost requirements have become more and more strict. At the same time, due to the increase in labor costs and the increasing complexity of traditional part designs, traditional enterprises have a very urgent need for hydraulic fixtures (hydraulic fixtures have high machining efficiency, stable dimensions, and low labor intensity). The fixture design of traditional horizontal machining centers often requires the separate design of the entire hydraulic system and structure, resulting in a small variety and quantity of machined parts. Moreover, when the workpiece needs to be frequently changed, since it takes a certain amount of time to clamp and disassemble the workpiece before and after workpiece machining, the workpiece clamping cannot meet the machining beat in time, resulting in a certain machining waiting time and affecting production efficiency; parts with high development costs, small batches, high precision, and low-cost requirements cannot use hydraulic tooling. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a rotary table for a horizontal machining center, which can be applicable to different types of machining workpieces, can quickly replace tooling, reduce the design workload, reduce the fixture cost, improve work efficiency and machining accuracy, and has high versatility.

[0004] To solve the above technical problem, the present invention provides a rotary table for a horizontal machining center, including a machining center machine tool, a load-carrying main body, a hydraulic device, and a telescopic support.

[0007] Furthermore, the first hydraulic oil inlet interface and the first hydraulic oil outlet interface are respectively connected to a hydraulic station provided outside the machining center machine tool through a first oil pipe, and the first oil pipe passes through the inside of the telescopic support.
